The present invention relates to an environmentally friendly soft ground sewage culvert structure, and more particularly, in connection with the planting trees on the roadside located on the soft ground to maximize the settlement and flotation of the culvert by the ground subsidence and groundwater buoyancy. It prevents and supplies the water necessary for the growth of planted roadside trees, and enables to purify the river water flowing into the culvert through the root roots of the roadside trees, and the groundwater contained in the soft ground can be filtered to flow into the ground. The present invention relates to an environmentally friendly soft ground sewer culvert structure that can be solidified.

In general, sewage refers to sewage, wastewater and rainwater discharged from homes and factories.

In addition, the sewage collecting the sewage is composed of a sewage pipe facility, a sewage treatment facility and a sludge treatment facility.

Here, the sewage pipe facility is a general term for facilities including a culvert and an open type of conduit, sewage receiving basin, storm drain, manhole, storm drain, earthenware and connector, etc. It plays a role of collecting sewage, wastewater and rainwater discharged from industrial areas, etc., and dropping them to treatment plants or discharged waters.

For reference, these sewage pipelines are based on the soil of the location where they are constructed (divided into hard, ordinary, soft, and soft soil). In order to prevent pipe corrosion and sedimentation, each foundation (sand or crushed stone and concrete foundation) is used. ) Should be installed in different combinations.

That is, sand or crushed stone is laid in the longitudinal direction in accordance with the state of the soil in the crushed ground, or after the installation of the foundation-based PC concrete joints are connected to the conduit to the upper part, and then backfilled to achieve the construction.

However, the conventional sewage pipe facility constructed in this way does not have much problem when installed in hard soil and ordinary soil, but when it is installed in soft soil and soft soil where sedimentation occurs seriously, When the earth pressure caused by unequal settlement and groundwater buoyancy is transferred, it often fails to respond effectively, and serious problems such as severe damage and breakage of the foundation and sewer pipes occur frequently.

This is because the sewage pipes constructed in the conventional soft soil are in fact rugged and fragile.

As a result, a large amount of unintentional wastes and wastewaters were leaked to the outside during actual use, causing serious environmental pollution of the ground and groundwater, as well as causing serious odors to the surface.

In addition, such defects frequently occur, there was an uneconomical and inconvenient problem of enormous maintenance and periodic management.

In recent years, the development of conduits to solve these problems has been progressing at various angles.

An example (registration utility model 20-0261920) is located in the longitudinal direction connected to the surface of the rupture, the lower groove is formed at equal intervals, the fixed anchor rod of a certain length is inserted into both sides extended An anchor hole is formed so that it can be formed, and a semicircular settled part is formed at the upper part, and a supporting PC is provided with a plurality of binding grooves and separation prevention holes formed at both the front and rear sides and the upper and rear upper parts to allow insertion and fixing from the outside. Concrete;

A circular sewer pipe formed of a high-density polyethylene material connected to the semi-circular settled portion of the supporting PC concrete through adhesive mortar;

A bellows connector which is installed on the outer periphery of the joints of the circular sewer pipes connected to the semi-circular settled portion of the supporting PC concrete to prevent mutual separation;

It is integrated into the binding groove and the separation prevention holes located in the front, rear and front, rear upper part of the upper portion of the support PC concrete, and includes a binding port and escape prevention unit integrally to prevent separation of the support PC concrete and the circular sewer pipe. There is one configured.

However, the conventional design configured as described above has a monotonous problem that there is no other additional function because it is manufactured only in consideration of the function of preventing the culling of the culvert connected by earth pressure due to uneven settlement and groundwater buoyancy.

In addition, in addition to the problem of impeding the growth of the root roots that grow and grow in the trees planted in the adjacent ground, there were many cases in which the connection state is separated by these roots.

In addition, the above-described culvert prevention structure has a problem in that the connection between the culverts is firmly established using the configuration in which the installation is made in the ground, and thus, the actual intended action cannot be effectively achieved.

In other words, as described above, all of the structures and configurations for maintaining the connection state of the culverts installed in the soft ground are located in the ground, so when the change of the culvert connected by the fluctuation of the soft ground is made, the connection of the culverts is made. This is because all the components to strengthen the state also work together at the same time.

The present invention has been made in view of the conventional problems as described above, the object of the present invention in connection with the planting roadside of roadside located on the soft ground ground sedimentation and flotation caused by the unequal settlement of ground and buoyancy of groundwater buoyancy It is possible to prevent the phenomenon as much as possible, to provide the necessary water for the growth of planted roadside trees, to purify the river water flowing into the culvert through the root roots of the roadside trees, and to filter the groundwater contained in the soft ground through the inflow. It is to provide an eco-friendly soft ground sewage culvert structure to solidify the condition of the ground.
